A method for determining a die profile for forming a metal part having a
desired shape. The method includes the steps of providing a nominal die
profile, determining a springback profile based on the nominal die
profile and employing a compensation strategy to determine the die
profile based on the nominal die profile and the springback profile.
There are disclosed five (5) compensation strategies: (1) a reversed
die-normal technique; (2) a reversed radial rotation technique; (3) a
reversed resultant vector technique; (4) a reversed path technique; and
(5) a mirror image of resultant vector technique. Associated methods of
making a die based on the die profile determined above and making a metal
part under a set of forming conditions from the die are also disclosed.
